Each year, it is estimated that more than 2,000 people set out to thru-hike the Appalachian Trail, yet seven in ten ultimately fall short of their goal. Given the countless number of how-to books and websites offering information about logistics, gear, and endurance training, one would think that more people would finish this 2,200 mile trek. Why then, do so many hikers quit prematurely?After successfully thru-hiking the AT in five months with zero prior backpacking experience, author, Zach Davis, is convinced he’s discovered the answer. Aspiring thru-hikers, Davis tells readers, are preparing the wrong way- sweating on the StairMaster, meticulously plotting each re-supply box, or obsessing over the perfect sleeping bag or pair of socks.
